JOHN SLADE CARTER, OF BUFFALO, NEW YORK.

FEED-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 635,233, dated October17, 1899.

Application filed February 9 1899.

To all tvlwm it may concern.-

Be it known that I, JOHN SLADE CARTER, of Buffalo, in the county of Erieand State of New York, have invented a new and improved FeedaterApparatus, of which the following is afull, clear, and exactdescription.

This invention relates to feed-water apparatus in which exhaust-steamfrom the engine or other apparatus in connection with which the boileris used is led to the feed-water apparatus to heat the feed-water and atthe sameltime to condense the exhaust-steam and cause its return to theboiler.

My apparatus also embodies means for purifying the feed-water and forseparating oil from the exhaust-steam.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevation of my invention. Fig. 2 is a verticallongitudinal section thereof. Fig. 3 is a sectional view on the line 3 3of Fig. 2. Fig. 4 is a similar view on the line 4 40f Fig. 2. Fig. 5 isa similar view on the line 5 5 of Fig. 2, and Fig. 6 is a detailcross-section on the line 6 6 of Fig. 2.

The apparatus has a cylindrical casing 7, in the bottom of which isformed an annular chamber 8, having a blow-out pipe 9 in connectiontherewith. Leading into the chamber 8 is the contracted neck of acircular drum 10, in which is fitted a stationary screw 11. Theexhaust-steam is passed through the drum 10 in the direction of thearrow shown in Fig. 2, so as to be led into the steam-chamber 8. Thedrum 10 is formed with a number of longitudinally-extending slots 12therein, all of which lead into a curved receptacle 14, surrounding thelower portion of the drum and commanded by a petcock 15. The steamdriven through the drum is caused to have a spiral movement by the screw11, which by centrifugal action throws outward the particles of oil thatbe suspended in the steam, such particles of oil engaging the sides ofthe drum and passing through the openings 12 into the receptacle 14,from which they may be with- Serial No.705,018. (No model.)

drawn by way of the cock 15. By these means the oil is effectivelyseparated from the steam, which latter passes into the apparatus in apure state.

Leading up from the steam-chamber 8 is a pipe 16, which has openingsnear its upper end for the exit of the steam and which has ahorizontalbaffle-plate 17 secured to its up per extremity, causing the steam topass out horizontally into a feed-water-heating chamber 18. From thefeed-water-heating chamber 18 the steam passes bya pipe 19 to a box 20,which is in communication with a number of vertically-standingcondensing-tubes 21, constructed, preferably, of glass. The upper endsof these tubes arein connect-ion with a box 22 similar to the box 20, sothat the steam passes from the tubes 21 to the box 22 and from the box22 into a pipe 23, which leads into a second feed-water-heatin g chamber24. The steam passes horizontally across this chamber and out by way ofa pipe 25, which leads to a box 26 similar to the box and incommunication with condensing-tubes 27 similar to the tubes 21. Theupper ends of the tubes 27 communicate with a box 28 similar to the box22, from which box 28 passes a pipe 29, that leads into a thirdfeed-waterheating chamber 30, which is located at the upper extremity ofthe casing 7. From the box 26 a trapped or return pipe 36 leads to the'feed-water-heating chamber 18, by means of which pipe the water ofcondensation from the elements 28, 27, and 26 is returned to saidfeed-water-heating chamber 18. From the chamber 30 the steam passes byway of a perpendicular pipe 31 to an annular box 32, which communicateswith a number of perpendicularly-extending condensing-tubes 33, leadingto a box 34 similar to the box 32. The box 34 has an outlet in the formof a vertically-extending pipe 35. The steam in its passage through thevarious compartments thus described is condensed, and the water ofcondensation runs back into the casing to be employed as feed water. Thesteam is also employed to heat the feedwater in a manner whichwill nowbe described.

The feed-water is led into the apparatus by means of a pipe 37, whichdelivers upon an imperforate concave baffle-plate 38. The water passesover this plate and upon a convex baffle-plate 39, located directlybeneath the plate 38, over which the water-passes in a spray, so thatthe steam entering the chamber 30 by the pipe 29 will act thoroughlyupon the water to heat the same. The chambers 24 and 30 are divided bymeans of a filteringpartition formed of an upper screen 40 and a lowerscreen 41, between which is packed a fibrous filtering material 42. Thewater from the chamber 30 percolates through the filtering material 42and'falls in a spray into the chamber 24, where it is again subjected tothe action of the steam passing between the pipes 23 and 25 to befurther heated. The chamber 24 is divided from the chamber '18 by afiltering-partition formed of an upper leads the same downward into awater-chant ber4S, located directly above the steam-chamber 8. Situateddirectly beneath the plate 46 is a feed-water chamber 49, from which thewater is led to the boiler by means of a pipe 50. The chamber 49 isdivided from the chamber 48 by a filtering-partition formed of an upperscreen 51 and a lower screen 52, between which is arranged a mass ofmineral filtering material 53, preferably coke. The chamber 49 isprovided with a water-gage 54, and this chamber also has a trappedoverflowpipe 55. A float-lever 5G is extended into the chamber 49, to beactuated by the water therein, and is connected by means of a link 57with the arm of a valve 58, controlling the pipe 37, so that the volumeof water delivered to the apparatus is regulated by the height of thewater in the chamber 49. The chamber 48 is provided with a valvedblowoff pipe 59.

The casing 7 of the boiler is provided with three manholes closed byplates 60, through which manholes access maybe had to the interior ofthe casing for cleaning the several filtering-partitions, and for thispurpose the upper filtering-plates 40, 43, and 51 are formed in two ormore removable sections, as shown with reference to the plate 43 in'Fig. 4, so that the plates referred to may be removed or partly removedand the filtering material reached.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A feed-water apparatus, having a casing formedwith a chamber at its lower end, the chamber having a steam-inlet, awater-chamber formed above the first-named or steam chamber, a pipepassing between the two chambers and leading the steam upward, afilteringpartiti on located in the casin g above the pipe, an outsidecondensing connection passing around the partition to lead the steampast the same, means for feeding the water to the upper end of thecasing, the water passing downward through the filtering-partition andbeing heated by the steam and the steam being condensed by the water,and a second pipe surrounding the first-named pipe and leading thefeed-water to the water-chamber.

2. In a feed-water apparatus, the combination of a casing, means forfeeding the steam to the casing at the lower portion thereof below thepartitions, means for feeding the water to the upper portion of thecasing above the partition, and a condensing connection outside of thecasing and communicating with the interior of the casing at each'side ofthe partition to lead the steam around the partition and to condense thesteam as it passes through the said connection.

A feed-water apparatus, having a casing with two filtering-partitionstherein, such partitions being separated from each other to form threechambers, a condensing connection located outside of the casing andpassing around one of the partitions, the connection communicating withthe adjacent chambers,

a second condensing connection located outside of the casing and passingaround the other filtering-partition and communicating with the twoadjacent chambers, a returnpipe passing from the second condensingconnection and leading into the lowermost of the said chambers, andmeans for feeding the steam to the lower portion of the casing and thewater to the upper portion thereof.
